The invention relates to new chemical coordinative structure compounds, namely to copper (II) and cadmium double salt with ammonia and orthophosphate ion in solid state of general formula CuCd(PО)n(NH)m(HО), where x=0.61.0; n=2.63.1; m=2.93.3. The process for the preparation of amorphous double salt copper (II)-cadmium aquaaminoorthophosphate, in which fixed ratio between the content of Cuand Cdis performed by solving of mechanical mixture of crystal Сu(РO)3НO and Сd(РO)5НO, taken in mole ratio Сu: Cdfrom 2.4 : 0.6 to 2.0 : 1.0, in concentrated ammonia water solution with further deposition of solid compound by addition of phosphate ammonia solution to the acetone, separation of bottom phase and its holding in air at 15-25 °С to complete hardening and constant mass. Thermolysis products of the prepared compounds further can be used as high-temperature pigment additives to dyes. |
